Our group is moving from @mpi-bio-fml.bsky.social to the maritime city of Kiel! ⛵️🩵 I will lead the Department of Marine Plant Development and Physiology @uni-kiel.de 🌱🪸🌊 Look out for opportunities to join us in this exciting & growing hub for Plant, Marine & Evolutionary Biology in North Germany 🇩🇪

61 species, 13 phyla, one simple geometric rule that appears to set when every embryo starts speaking through its own genome. 🧬 Panagiotis Giannios highlights a recent #preprint from @mirimiam.bsky.social & collaborators. #EvolutionaryBiology #preLight: prelights.biologists.com/highlights/e...

The rise of polyploids during environmental upheaval

From the dating of 132 ancient whole-genome duplication events across 470 angiosperms, paleopolyploidization events cluster around pivotal periods of environmental upheaval and extinction, notably the...

We are very happy and proud to present a study led by @jorgehg.bsky.social (now PI in Madrid – keep an eye on him!) in our team @bic-wur.bsky.social. In this work, we discover how auxin-regulated ARF transcription factors learned to activate transcription. A 🧵…(1/17) www.biorxiv.org/content/10.6...

This finding provides broad comparative support for the longstanding hypothesis that the nuclear-to-cytoplasmic (N/C) ratio acts as a timer of genome activation. Moreover, this scaling accurately predicts ZGA timing across diverse animals from genome size and egg volume of a species alone. 8/15

🌊 New preprint! Maternal-to-zygotic transition across the isogamy–oogamy continuum in brown algae. In animals, maternal provisioning delays ZGA. In brown algae, it appears to support it: fast and continuous in oogamy, biphasic in near-isogamy with a delayed wave. 🔗 doi.org/10.64898/202...

Does trait choice change the outcome of hybrid Species Distribution Models under climate change? We tested this and fond that correlative & hybrid models converged, both pointing to future range contractions. Read at: doi.org/10.1002/ecog... #Marinebiology #climatechange #machinelearning

Genome editing in brown algae! 🧬🪸🌿 Now out in Cell Reports Methods! Excited to share this highly efficient, transgene-free CRISPR–Cas genome editing protocol for brown algae, requiring no cloning and no specialized equipment. doi.org/10.1016/j.cr... #CRISPR #BrownAlgae @mpi-bio-fml.bsky.social

New CRISPR tools for brown algae: a transgene-free genome editing methodology, developed in Ectocarpus and validated in kelps such as Undaria pinnatifida, opens new possibilities for functional genomics, aquaculture, and blue biotechnology. Online ahead of print: doi.org/10.1016/j.cr...

New research: With ancient origins & surprising flexibility, #BrownAlgae reveal a compelling story of sex chromosome evolution. This could rewrite how we view sex determination. Learn more: s.gwdg.de/YDoZ3L Congrats to @agalip.bsky.social & Josue Barrera for their work in @natecoevo.nature.com

Genomes of brown algae with different sex determination systems show that U/V sex chromosomes evolved 450–224 million years ago and show remarkable conservation of genes within the sex-determining region, despite independent expansions of the sex locus in each lineage www.nature.com/articles/s41...

Excited to share the Phaeoexplorer paper out today in Cell: Evolutionary genomics of the emergence of brown algae as key components of coastal ecosystems! 🌊 Including the genome of Dictyota dichotoma and many more! doi.org/10.1016/j.ce... #Seaweed

🌊✨ Excited to share our new review in Development on the molecular bases of multicellular development in brown algae! 🌿🔬 #BrownAlgae #EvoDevo #Multicellularity #DevelopmentalBiology Link: doi.org/10.1242/dev....

Great to see our work on AB-polarity in kelp online and the hard work of the last 3 years by some young scientists valorized! 🌿🔬 Big shoutout to Eloise Dries, Yannick Meyers, Floriele Gonzaga, and Jakob Becker and all involved. It was a pleasure! 🙌 doi.org/10.1111/nph....
